    Abstract

    The impact of citrus vein phloem degeneration (CVPD) on biological characteristics of Diaphorina citri on Siem citrus was studied in the laboratory. Cohorts of the psytlid consisted of 100 eggs were cultured in the laboratory on both healthy and CVPD infected Siem citrus,and 150 nymphs of fourth instar in the field cages. CVPD affected significantly reproduction rate, age, survivorship and sex ratio of the psyllid. It significantly shortened the age of female (18-61 days on healthy citrus, 14-35 days on infected citrus), decreased fecundity (457.8 eggs/female on healthy citrus, 201.8 eggs/ female on infected citrus), decreased survivorship of second instar nymph (48% on healthy citrus, 32% on infected citrus), increased the ratio of male/female (0.868 on healthy citrus, 1.355 on infected citrus), and decreased the intrinsic rate of increase (r = -0.009 on healthy citrus, r = -0.021 on infected citrus).
